Title: Forward error correction on multiplexed cdma channel enabling high performance coding
Inventor: FERGUSON DENNIS D
IPC: H04L47/43
Filed: 2011-06-15
Abstract: <P>PROBLEM TO BE SOLVED: To provide a communication method of data related to forward error correction on multiplexed CDMA channels enabling high performance coding, regarding a protocol for optimizing the use of coded transmissions such as over wireless links.  <P>SOLUTION: In this technique, interframes are first split into segments selected to be an optimum size according to transmission characteristics of a radio channel. A position identifier and redundancy check sum are assigned to each segment. Segments are then assembled into blocks and a forward error correction algorithm is applied to the block to generate redundancy bits. The FEC block is then split up among available communication channels and forwarded to a receiver. The inverse process is applied to the receiver, Use of this scheme is needed to be applied only to segments containing erroneous data. Therefore, a large block size required for high performance forward error correction may therefore be used while, at the same time, minimizing latencies associated with the need to resend entire blocks when errors cannot be recovered.  <P>COPYRIGHT: (C)2011,JPO&INPIT
